Hey guys! I actually managed to open the other half. here is the link to the video! Thanks! ua-cam.com/video/zLrlEsf_wG4/v-deo.html
You’re a lifesaver for this video. I have a 2015 si supercharged and my impeller snapped as well. I have the thing apart but how do you remove the impeller shaft?
@@alejandroserrano5476 it’s difficult bro. You would honestly have to take it to a professional. Looking back at this vid I completely screwed the unit taking it apart. It’s very intricate and precise, be weary. You will need a bearing press for reassembly if you do decide to do it on your own. Thank you for watching and I hope this helped! Keep me updated!
That's Rotrex for ya. I have their stage 3 on my yamaha apex and have put tons of miles on it. It owes me nothing. But when they first came out I put the stage 1 kit on my first apex and the charger didn't make it 100 miles before grenadeing so there are lemons and they're solid units
Hi, I have a Ford Fiesta Zetec S Mk7 with a Rotrex supercharger. Mine failed a few months back. Although your issue may not be to do with anything "wrong" with you oil lines it is likely caused by your bearing being starved of oil. This is because the supercharger, and in tern the oil pump I assume is being run on the auxiliary belt and when you shut off the car the auxiliary belt stops rotating in tern stopping the oil pump from running, even though the bearing will still be spinning like mad. This means the bearing is still running but is not being lubricated. This is why it's important to let your car run idle for a few minutes before shutting it completely off.
max stone that makes sense. I never thought of that. I always started up the car and let it warm up before I drove it but I never kept it running for a little when I was done. Thanks for your input! How’s your car doing?
@@TommyMccoyMedia Hi mate, sorry for the delayed reply. My car's doing okay thankyou mate, it's n/a ATM but am looking to get the supercharger back on it 😀. Hope your cars all well!
This is the ONLY channel i've found with a rotrex strip down. It would be Sooo useful if you can show the planetary gears too. My rotrex seized. I thought it was oil but i opened part of it and plenty of oil poured out.
I later found my oil supply line was blown in two places. I think the oil became trapped in a vacuum and overheated inside the S.C not being able to circulate back through the cooler.
I can't see any damage yet but i initially could not rotate by hand until i opened it up, then it freed up.
QUESTION:
Is it normal to feel a notchy movement during manual rotation of the pully gear?
Why do you suppose i could not initially rotate the seized pully drive wheel before opening it up?
Thanks for any advice.
Zion2030 hey man welcome to the channel!
I'm glad you found this video useful. I will be doing another video in the near future exposing the planetary gears. I tried getting in to them but it is extremely tough to crack. I am currently trying to find a way to bust it open. BUT, I will! Keep checking in. I'm quite busy with school and getting ready to graduate college that I have no time at all. I appreciate your patience!
To answer your question about the notchy movements, I may have. There was a subtle grinding noise while the car was running but I couldn't figure it out. Then this happened. It could be your impeller rubbing along the housing. The planetary gears are very well protected so I don't think any corruption is likely in there unless you overspin the charger.
Hope all is well and that it was something minor for you. Let me know if anything new comes up!
In case you had not found the answer, yes, the notchy or resistant manual turns are normal. The unit uses a gerotor style oil pump that causes this.
Please keep us posted on what you find. It's crazy is that I have had the exact same experiences with the KW kit... My pulley fell off the same way and now mine is also making a funny noise a few years later. Of course, I also replaced the bearings in the idlers because they were also shot before I found this video.
*I couldn't sleep and I think I have a theory on why your unit failed. I believe the failed input bearing alowed the entire planetary gearset to bend/shift from the weight of the drive belt. This shift allowed your turbine to contact the compressor housing and sheered the shaft right off.
Anyways, thanks for the info Tommy Mccoy
Anthony Chung that's actually what it was. That's what my dad was saying and it's the only thing that makes sense. The input bearing was shot. I feel as though kraftwerks knows this is an issue but they don't care. It keeps them in business. It sucks, I loved my kit.
Thank you for watching though bro! Learn from my experience and have a look through your unit and see if there's anything.
Have you considered buying parts from www.superchargerrebuild.com/rotrex-rebuild/ ? The only thing is that you'd have to get the impeller balanced with a new output shaft at a turbo rebuilding shop.
I have! but they quoted me $65 to look at it and $675 if it's fixable. To be honest I have no interest in going through this struggle again. This experience has further solidified my stance on how I feel about Rotrex and their units. Hopefully come january I can get the Greddy Turbo :)
wow what a bummer about the state of the Rotrex, I feel your pain dude!!
Is the Rotrex fixable or is it now junk? would you put another on or replace with something else?
Good luck and best wishes, whatever the plan is!
The kit is good, it's just I would have to buy another rotrex unit. After seeing this I am not willig to buy another one, I would rather go with another set up that does not have the reputation of breaking so easily. Currently n/a, enjoying it too oddly enough! I'd like to go turbo next year after I graduate college! Thanks for stopping by man :)
great video bro! learned alot about the supercharger with this vid
Thanks bro! We're trying to expose the planetary gears within the rotrex to see of the other bearing is shot. Regardless, it's cool opening one of these up. Cheers man!
the bearing could have failed first and the shaft breaking a result of that? thanks for sharing this!
Bart Van de Velde exactly what happened :/. No problem! I hope I brought some answers to you!
At 5:26 it clearly shows the drive gear has wobbled and worn a groove on the bearing housing, evidence that the bearing broke first. Dry and rusty bearings do that eventually. Thanks very much for the dissection though...good job!
Thanks for watching bro! 🙏🏽 I appreciate it!
Same shit happened to mine, upgraded to the 38-94
Go with a turbo, some kits are designed so you can change out the turbo, put a bigger one or go with a different manufacturer. I'm personally going with a garrett turbo, heard nothing but great things about them.
Bryan R yeah that's why I'm contemplating it. :) but we shall see honestly. Right now I'm just trying to graduate college! Lol
Hey Man great video, it was very informative! Im sorry for you and your build, but like you said it can be a positive thing in the end! Im also from El Paso and maybe one day we can make a collab of some sort, been a sub of yours for a bit of time now, Keep up the vids!
Dude holy crap! I appreciate the positivity man. Things happen haha, At least this gives me a chance to redo the direction of the build so it's sweet and sour lol. Of course bro! would love to meet you! #ChucoFam
Great vid..hope you get your car sorted soon.. what's ur next step? Turbo route or different supercharger brand?
ill RuiNzZ Gaming right now I have reverted back to stock. :) I want to go turbo next but not until next year. God willing. Thanks man!
Now, if I am not mistaken that damage is caused by hitting limiter way too often. Planetary gear systems do not like hitting limiter. Rotrexs are suprising delicate units. Those input shafts are useless though
Rotrex is better than eaton, g60, or turbo k26?
Was there no warranty on that supercharger?
That's not supposed to happen at all :(
there is but they sell you one at a discounted price after you ship it to them. I bought the kit new from a guy who got his wife pregnant so distributor warranty is also not a possibility. live and learn lol.
My rotrex just broke too, i dont know what i can do, i used it only 14 months, .........
Acube24 frustrating ain't it? ... we need to petition against rotrex. Poor designs. Nothing but broken chargers across many platforms so you know it's not just a specific model. It's all rotrex units.
For sure i want a petition, i m waiting answer, but for short time, i get out all thing , i returned stock, but i m so frustrating, shit part, broke after one years......, i lets my garage negociate, i will let you know, the bad thinh i lost waranty of toyota for 1 year SC, fuck off....
Few questions:
when was the fluid last changed?
how many time was the limiter or lunch control used?
what millage did the unit cover before failure?
Thank you for watching!
Had about 20k miles on the supercharger. Was about to change the fluids.
Launch control and rev limiter was used occasionally. I learned that bouncing the limiter really jacks up the procharger and it makes sense.
I did not have warranty as I got it through another owner. Kit was brand new but he had to sell it because his wife got pregnant lol.
@@TommyMccoyMedia what did it fail on in the end?
How long did the supercharger last you? I was going to get a kit but I think I might just go turbo
About 2 years.
If you get it, have warranty info readily available. Thanks for watching!
How long did it last you b4 the failure? This happens alot on civic si's same problem same charger
20k miles my dude. :( I see that all rotrex's are like this. It keeps the consumers in the market. I will never own another rotrex unit kit.
Tommy Mccoy this blows man. Just got mine about 1000 miles ago, I'll be looking into getting a turbo around 13000 miles. Going to sub my, dude!
MrjdmZombie Garcia I appreciate you checking in! Yeah, that or just be aware of the bearings. Run a check every couple thousand miles.
Tommy Mccoy will do my dude
That really sucks to hear. Do you think Jackson Racing rotrex would make any difference compared to Kraftworks?
“Got the kit from a guy who knocked up his wife” LOL
Fugazi Garage I probably could have worded that better 😅 lol. Thanks for watching!
😂 no worries I thought it was funny
How the hell did u get the pulls bolt off mine is like stuck on
MR DIYV8 some elbow grease man. Sucker was not easy to open up. Takes a while of prodding and wiggling. Should give in. Thanks for watching man!
Tommy Mccoy I ended up pulling mine apart the same night, my c30 was wrecked inside because one of the bolts they used to hold the bearing “cage” in place came loose....
MR DIYV8 Jesus man 🥴. Sorry to hear about that. What’s next? Are you going to rebuild or just scrap the kit? Wishing you the best. 🤞🏽
Tommy Mccoy probably just reassemble it polish it and have a C30 paper weight I had. Priced out a total rebuild and it’s almost 1200 bucks
MR DIYV8 that sounds badass. I left mine in El Paso with my dad. Moved to SA. I’m going to turn it into a desk lamp!😂👍🏽.
Great video. I appreciate you taking the time to learn and attempt it yourself. You mentioned that you were able to order spare parts for the supercharger? Where did you order them from? Thanks
Michael Escay I had the opportunity to, but decided not to. Reason being is the parts and the only known person that could fix these things charges an arm and a leg. At that point it’s just better off buying a new unit straight from rotrex at a “discounted” rate. :/.
You can get the parts at Superchargerrebuild.com
@@TommyMccoyMedia where and how much did you pay for the discontinued replacement unit?
Man, I have the SAME EXACT issue with my procharger unit :(
Sorry to hear that bro:/. I literally think they design these things to fail so we can continue buying them at discounted warranty prices.
Great video!
Do you know the diameter of the impeller?
Thanks man! I don’t remember it off the top of my head. It’s somewhere deep in the Rotrex site with the manual. But this website here sells replacements with the 7mm bore required. Hope this helped 🤞🏽👍🏽. Thanks for watching!

Get Paxton?
What is the trim of this compressor wheel?
liked and sub'd because I may be in the same boat :/ if you have any leads on replacement parts please share
G Corry thanks for the support brodie. Superchargerrebuilds has replacement parts available but you’d have to find someone to balance the parts. 🥴.
trump said not to buy china things , i approve this message
5413rlonda 😂😂 I concur.
